In combination with the above embodiment, the use principle and working process of the present invention are as follows:

The installation springs are compressed to enable the telescopic columns 537 to approach each other, the upper supporting rods 533 are inserted into the upper cross rod 510, the lower supporting rods 534 are inserted into the lower cross rod 520, when the telescopic columns 537 are opposite to the limit sliding grooves 513, the installation springs restore to a natural state, the telescopic columns 537 are inserted into the limit sliding grooves 513 on the front side and the rear side, the limit sliding grooves 513 and the telescopic columns 537 are matched to complete the guiding function on the telescopic rods 530, and the pulleys 621 are slidably installed in the transverse sliding grooves 512.

The limiting block 421 is inserted into the limiting slot 411, so that the beam support 420 is installed below the main beam 410; the main beam 410 and the bracket 420 are then mounted above the upper rail 510 and fixedly connected by bolts.

The handle is rotated, the length of the base 310 inserted into the supporting rods 300 is adjusted to adjust the height of the supporting rods 300 to reach a preset height, then the supporting beam assembly 400 and the jacking assembly 500 are installed between the two supporting rods 300 to be in the state of fig. 5, at this time, the telescopic rod 530 is in an inclined state and has the shortest length, the auxiliary spring 630 is in a natural state and is not stressed, and the limit bolt 710 on the lower cross rod 520 is rotated to keep the height of the lower cross rod 520 unchanged; another support mechanism 200 is then assembled in the same step and the template body 100 is placed over the main beams 410 of both support mechanisms 200.

Thereafter, the telescopic link 530 is twisted counterclockwise to be in a vertical state, as shown in fig. 6, and the upper cross bar 510 is gradually moved upward in the process of tilting the telescopic link 530 to be in a vertical state, and the formwork body 100 is driven to be simultaneously moved upward by the girder assembly 400; moving the telescopic rod 530 to the midpoint connecting line of the upper cross bar 510 and the lower cross bar 520, as shown in fig. 7, so that the upper cross bar 510 is uniformly stressed and kept in a horizontal state; then two persons simultaneously rotate the main sleeve 532, and as the main sleeve 532 and the main rod 531 are matched through threads, when the main sleeve 532 is rotated, the telescopic rod 530 stretches to enable the template body 100 to move upwards to the highest position, and at the moment, the upper surfaces of the main beam 410, the template body 100 and the baffle are flush; as shown in fig. 8, the wedge block 720 is inserted into the limit groove 303 under the action of the limit spring 730, so that the height of the upper cross bar 510 is kept unchanged and the pressure applied by the telescopic rod 530 is shared; in the process of rotating the main sleeve 532, since the plurality of balls 536 are installed between the blocking sleeve 535 and the main sleeve 532, friction is reduced, the abrasion speed of the main sleeve 532 and the blocking sleeve 535 is slowed down, and construction cost is reduced.

Upon continued rotation of main sleeve 532, telescoping rod 530 is no longer extended; thereafter, while rotating the main sleeve 532, twisting the main sleeve 532 clockwise to make the telescopic rod 530 in an inclined state, during the process of twisting the telescopic rod 530, since the length of the telescopic rod 530 is unchanged, the upper cross rod 510 and the components mounted above the upper cross rod 510 have a descending trend, one ends of the two auxiliary rods 620 which are respectively connected to the upper cross rod 510 and the lower cross rod 520 in a sliding manner are subjected to the pushing force of the corresponding upper cross rod 510 or the lower cross rod 520, the two auxiliary springs 630 are compressed, the auxiliary rods 620 move into the auxiliary sleeves 610, the trend of the auxiliary springs 630 restoring the natural state causes the auxiliary rods 620 to have an upward pushing force on the upper cross rod 510, and the trend of the telescopic rod 530 to restore the vertical state is also caused, so that the heights of the upper cross rod 510 and the components mounted above the upper cross rod 510 are ensured to be unchanged; the auxiliary rod 620 and the wedge block 720 share partial pressure applied to the telescopic rod 530 at the same time, so that work done by a worker when the telescopic rod 530 is twisted is reduced, and the effort is saved; after the telescopic rod 530 passes through the dead point shown in fig. 8, only the main sleeve 532 is required to be rotated, so that the telescopic rod 530 can be rotated clockwise and extended continuously until the telescopic rod 530 is extended to the state of fig. 9, and the upper and lower ends of the telescopic rod 530 respectively prop against the two corners of the upper cross rod 510 and the lower cross rod 520. Then lifting a corresponding number of template bodies 100 according to construction requirements, and when the subsequent template bodies 100 need to be lifted, supporting mechanisms 200 of two adjacent template bodies 100 share a supporting rod 300, and supporting mechanisms 200 of two left and right adjacent template bodies 100 are respectively arranged on vertical sliding grooves 302 on the left side and the right side of the same supporting rod 300; the invention solves the problem that one template body 100 cannot be lifted at a time during installation and removal, and a plurality of template bodies 100 must be lifted at the same time, and has stronger practicability.

After the required number of template bodies 100 are installed, a casting work is performed. After the pouring operation is completed, according to the solidification degree of the floor slab or beam, when the template body 100 needs to be removed, the main sleeve 532 is rotated, the telescopic rod 530 is shortened and the vertical state as shown in fig. 8 is restored, the main sleeve 532 is continuously rotated, the telescopic rod 530 is shortened, the supporting force for the upper cross rod 510 and the components mounted above the upper cross rod 510 is reduced, when the supporting force is smaller than the weight force of the upper cross rod 510 and the components mounted above the upper cross rod 510, the wedge block 720 gradually moves into the upper cross rod 510, the limit spring 730 is compressed, the support rod 300 is gradually separated, and the upper cross rod 510 and the components mounted above the upper cross rod 510 slowly move downwards; until the length of the telescopic rod 530 is shortest, as shown in fig. 7, and then the telescopic rod 530 is moved to the state shown in fig. 6, in this process, the heights of the upper cross rod 510 and the components mounted above the upper cross rod are unchanged, and then the telescopic rod 530 is twisted counterclockwise, so that the telescopic rod 530 is inclined, and at the same time, the upper cross rod 510 and the components mounted above the upper cross rod are gradually lowered, and after the state shown in fig. 5 is reached, the limit screw on the lower cross rod 520 is rotated, the limit effect on the lower cross rod 520 is released, and the telescopic rod 530, the upper cross rod 510, the beam support 420, the main beam 410 and the template body 100 are sequentially removed from the lower end of the guide bar 301, so that no overhead work is required by workers, and potential safety hazards are avoided. Or the jacking assembly 500 and the supporting beam assembly 400 are integrally removed from the lower ends of the guide bars, thereby reducing the mounting and removing processes, accelerating the construction progress and improving the construction efficiency. After the formwork body 100, the jacking assembly 500 and the support beam assembly 400 are removed, transferred to other positions or floors, and after the strength of the laminate or the beam reaches the standard, the support rods 300 are removed, so that the construction period is shortened, the construction labor productivity is improved, the input quantity of the formwork body 100 is reduced, and the construction cost is reduced. Because the upper cross bar 510 and the lower cross bar 520 are identical in structure, the upper cross bar 510 or the lower cross bar 520 does not need to be distinguished when the installation is performed, the universality of the upper cross bar 510 and the lower cross bar 520 is enhanced, and meanwhile, the installation speed is increased, so that the installation efficiency is improved.
